The Jacob & Co. Bugatti Chiron Sapphire Crystal

The transparency of the 55mm x 44mm case of the Bugatti Chiron Sapphire Crystal is the result of hand polishing – the final task of a long and complex process that took upwards of 120 hours to complete. The angles to polish the exteriors and interiors of the case are different. But the quality must be consistent. #jacobandco #jacobandcowatches @bugatti
